If the parameter list of a documented method consists of one or no parameters, the closing parenthesis has the color of the parameters - not the color of the opening parenthesis (and the name of the method).  Also, if there is exactly one parameter, the closing parenthesis follows this parameter without any separating blank, whereas there is a blank between the opening parenthesis and this parameter (my coding style uses blanks after the opening and before the closing parenthesis of a parameter list).  For two and more parameters, this is not an issue, as all parameters are listed on separate lines, and the closing parenthesis too is on its own line (and in this case has the correct color).

This is really a very minor issue (at least in its appearance), but thus far it is the only thing I found wrong with doxygen.  I am using doxygen for a mid-sized (~ 40kLOC) project with code in html/CSS, JavaScript, PHP, Python, C, and C++, and I am it EVERYWHERE. 

Thanks for doxygen - I LOVE it!!!!!
